Understanding the Assertion and Reason
The assertion (A) and reason (R) revolve around the processes of plant reproduction and evolution.
Assertion (A): Zygote Development
- The development of zygotes into young embryos occurs within the female gametophytes.
- In flowering plants (angiosperms), the zygote is formed after fertilization and develops into an embryo inside the ovule, which is part of the female gametophyte.
- This process is crucial for the formation of seeds, as the embryo is a key component of the seed.
Reason (R): Seed Habit Evolution
- The development from zygote to embryo is a precursor to the seed habit.
- Seeds are considered a significant evolutionary advancement because they protect the embryo and provide it with nutrients.
- The evolution of seeds enabled plants to reproduce successfully in diverse environments, thus enhancing their survival and adaptability.
Evaluation of the Options
- Given that both the assertion and reason are accurate, the correct choice reflects that R explains A.
- R describes why the process mentioned in A is evolutionarily significant, linking the development of embryos to the evolutionary advantage provided by seeds.
Conclusion
Thus, the correct answer is:
- a) Both A and R are true, and R is the correct explanation of A.
Both the statement about zygote development and the importance of this process in the evolution of seed plants are true, highlighting a critical evolutionary step in plant biology.

Solution:
Correct answer: 1. Both A and R are true, and R is the correct explanation of A.
Correct answer: 1. Both A and R are true, and R is the correct explanation of A.
Explanation: The development of the zygote within the female gametophyte provides protection and nourishment to the embryo, which is a key evolutionary step leading to the development of seeds in higher plants. Thus, both the assertion and reason are true, and the reason correctly explains the assertion.
Line in NCERT: "The development of the zygotes into young embryos take place within the female gametophytes. This event is a precursor to the seed habit considered an important step in evolution."
